AbstractFast growing cities and arid climate characterize northern Baja California, Mexico and Southern California in the United States. This paper presents a quantitative approach to identify promising water management alternatives, to cope with demands northwestern Baja California for year 2025. The California Value Integrated Model (CALVIN) is used as the main analysis tool to undertake this analysis. Economic water demand functions for urban and agricultural water uses in the cities of Ensenada and Tijuana, Baja California were estimated and used as an input for CALVIN. Water supply alternatives for year 2025 in Baja California include expanded infrastructure capacity, wastewater reuse, seawater desalination and aquifer overdraft. Results show that wastewater reuse can significantly reduce projected water scarcity and its costs for year 2025. In contrast seawater desalination seems to be a less promising alternative if its costs remain as high. This systems approach could effectively shed some light on future directions for water planning in this and other hydrologically connected regions including Southern California.
